SAW-OILING DEVICE.

Specification of Letters Patent.

Patented Aug. 14, 1906.

Application filed July 20,1905. Serial No. 270,592.

To all whom it vnay concern.-

Be itknown that I, LUTHER F. STEWART, a citizen of the United States, residing. at Stephenville, in the county of Erath and State of Texas,- have invented new and useful Improvements in Saw-Oiling Devices, of which the following is a specification.

My invention has relation to new and useful improvements in saw-oiling devices, and has for its object the production of a device of this class by means of which the blade of a saw may be oiled in an expedient and convenient manner.

With these ends in view my invention con sists inthe novel construction, combination, and arrangement of parts as hereinafter shown.

In the accompanying drawings, in which like parts are designated by like characters throughout the several views, Figure 1 is a side elevation of my invention secured in position to a saw-handle. Fig. 2 is a side elevation of a saw-handle and saw-blade with my invention in side elevation as secured thereto, part of the saw-blade broken away. Fig. 3 is a vertical transverse sectional view of my invention cut on the line X X of Fig. 2.. Fig. 4 is a vertical sectional view of one of the members of my invention.

My invention is described as follows: The numeral 1 represents a saw-handle, said handle being constructed or manufactured in such a manner as to admit of my im roved saw-oiling device 2 being secured t ereto. The numerals 8 represent oil cups or receptacles for holding the oil, said oil-cups terminating at their lower ends in working barrels 4. 5 represents vertical openings to allow the oil to pass from said oil-cups to said working barrels. The front ends of said barrels 4 are provided with internal threads adapted to mesh with the external threads of a nozzle 6, and thus hold said nozzle in position. Each of the twin members of my invention is of identical construction and are each provided with an inner wall 7 and outer wall 8, each of said inner walls in turn being provided with a central perforation, said members being held securely together by means of a screw 9, its threaded part meshing with the threads of said perforations. A saw-blade 10 is secured in position to said saw-handle 2 by means of screws 11. Pistons 12 are slidably secured in said working barrels 4, said pistons being adapted to be reciprocated by means of piston-rods 13, one of the ends of which are secured to said pistons, their other ends passing through perforations in said working barrels, thence outwardly through slot-perforations 14 and terminating in stops 15, said stops limiting the longitudinal move= ment of said pistons 12. When said pistons are in their normal position, they close the lower part of said openings 5, and thus pre vent the oil from passing from the said-oilcups to said working barrels. Said pistonrods are also provided with spiral springs 16, which encircle said pistons. My improved oiling device is also provided with two op positely-disposed threaded caps 16, the threaded parts of which caps mesh with the threads of perforations formed in the outer walls 8 of my improved oiling device.

When in use, I take hold of the stops 15 and pull the pistons 12, by means of the piston-rods 13, backward sufiiciently to uncover the lower parts of the vertical openings 5, the oil in said oil-cups passing through said openings and into the working barrels 4. I then release the said stops 15, and the piston-rods actuated by the said spiral springs drive the pistons forward and force the oil out of the end of the said nozzles 6 onto the saw-blade, the said stoppers cutting off the supply of the oil in the working barrels by re-covering the bottom of said vertical openings.

It will be apparent that my improved oiling device is of such construction that I may oil either side of the sawblade or oil both sides of said saw-blade simultaneously and separately.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A saw-oiling device 2, consisting of two members, said device secured to a saw-handle; oil-cups 3, formed in said members; working barrels 4, provided at the lower ends of said cups, said barrels provided at their front ends with internal threads; vertical openings 5, running from said cups to said working barrels; nozzles 6, provided at their rear ends with threads, which mesh with the threads of said working barrels, said nozzles being thus held securely in position, said members and cups being provided with walls 7, at the inner sides of said members, each of said walls provided with a perforation; walls 8, at the outer sides of said members, said members held securely together by a screw 9; pistons 12 slidably secured in said working barrels 4; piston-rods 13, secured at one end to said pistons, their other ends passing through perforations in said working barrels, and thence outwardly through slot-perforations 14, and terminating in stops 15, which 5 limit the longitudinal movement of said pistons, said oiling devices through the various devices and connections just described, adapted to oil a saw-blade, substantially as shown and described and for the IO set forth.

2. A saw-oiling device consisting of two members, said device adapted to be secured to a saw-handle; oil-cups formed in said members; working barrels provided at the 15 lower ends of said cups, said barrels provided 20 with the internal threads of said working barrels, said nozzles being thus held securely in position; walls, provided at the inner sides of said members, each of said walls provided purposes With-a perforation; walls, provided at the outer sides of said members, said members being held securely together by a screw or other equivalent substantial means; pistons, slidably secured in said working barrels, and piston-rods secured at their front ends to said pistons, their opposite ends passing through perforations in said working barrels, thence outwardly through slot-perforations, and terminating in stops, said stops limiting the longitudinal movement of said pistons, said oiling device through the various connections and devices just described adapted to oil a saw-blade by oiling both sides of said blade simultaneously or separately, substantially as shown and described and for the purposes set forth.

In testimony whereof I affiX my signature in presence of two subscribing Witnesses.
